嘉兴市出租车，起步价（2公里以内）为7元，超过2公里的按照每公里3元计算。要求根据路程计算费用

 

import java.util.Scanner;

public class E201_02_01_的士计价器 {
    public static void main(String[] args) {
        System.out.println("请输入公里：");
        Scanner scanner = new Scanner(System.in);
        int sceond= scanner.nextInt();
        float print;
        if (sceond>0&&sceond <=2){
        print=7;
        }else {
            if(sceond > 2 );{
                print =7+(sceond-2)*3;
         }
            System.out.println("费用为"+print);
            }
